Officer Brennan Rabain, 26, crashed while attempting to make a traffic stop around 3:20 a.m. in the 9500 block of Greenbelt Road in Lanham. Police said Rabain was off duty until he tried to conduct the traffic stop.

Rabain had been assigned to the District V (Clinton) station and was part of the department for less than two years.

Police said there was a woman in the car who suffered minor injuries in the crash. They said she was treated for her injuries at a hospital and was in extreme emotional distress.

Police said the woman had been sedated since Saturday morning and authorities have not been able to speak with her about the crash.

Authorities declined to identify the woman.

Officers have been authorized to wear mourning bands, according to Prince George’s County Police Chief Mark Magaw.

“He was a young officer,” Magaw said. “(He) loved this department. (He) loved this county.”

Those with information on the collision can call the Prince George's County Police Department Collision Analysis and Reconstruction unit at 301-731-4422. Those who wish to remain anonymous can call Crime Solvers at 866-411-TIPS.
